It offers a cooling capacity of 7200 BTU, which is effective for keeping the cabin comfortable in warm conditions. The unit runs on 12 volts, making it compatible with typical vehicle electrical systems. Its energy efficiency ratio (SEER) of 7.5 indicates moderate efficiency, balancing power use and cooling without being top-tier in energy savings.

Operating at about 50 decibels, this AC unit is relatively quiet for a truck air conditioner, contributing to a more pleasant driving and resting environment. Installation is easy, and the split system design helps improve airflow and heat dissipation, enhanced by a unique sun-shaped air outlet. The low noise function supports quiet operation when parked or driving with the engine off. Its size and weight are reasonable for the category but should be checked against space availability in the vehicle.

A key consideration is that the unit does not include refrigerant; users need to purchase and add R134a refrigerant separately. This process may require technical knowledge or professional assistance. The AC features standard controls, without advanced remote or smart features.

The Treeligo 12V Truck Air Conditioner is designed specifically for vehicles like semi-trucks, RVs, and construction equipment, offering a solid 12,000 BTU cooling capacity. This allows it to quickly lower the temperature inside your truck cab, which is especially beneficial for long hours on the road in hot weather. It uses inverter technology, enabling the compressor to adjust its speed based on cooling needs, which helps save battery power and ensures quiet operation at around 45 decibels—similar to a quiet conversation. The AC is powered by a 12-volt system compatible with your truck’s battery and can run with the engine off to reduce fuel consumption.

Installation is straightforward thanks to included accessories and instructions, and the durable ABS plastic housing resists corrosion and weather damage, making the unit suitable for harsh environments. While the energy efficiency is limited with a 1-star rating and a SEER of 1, indicating higher power consumption compared to other units, this may be a factor if you rely heavily on battery power without frequent engine running. The noise level, although relatively low, might still be noticeable in very quiet cabins.

The unit offers remote control and multiple operating modes (energy saving, sleep, powerful), adding convenience and flexibility. It also features a dehumidification function that can help reduce moisture inside the cabin. Backed by a 1-year warranty and positive customer feedback, it serves as a reliable cooling solution for truck drivers seeking easy installation and dependable performance, though it may not be the best option if minimizing battery drain over long periods is a priority.

The Mieligo 12V Truck Air Conditioner offers 10,000 BTU cooling power, which is solid for providing comfortable temperatures inside semi-truck cabs and similar vehicles.

The system is a split type with separate indoor and outdoor units, making it easier to install in trucks, trailers, and even equipment like cranes or RVs. It runs quietly at about 45 decibels, so it won’t add much noise to your cab environment. The brushless fan improves durability and keeps the noise low, which is helpful during long trips or parking.

A copper evaporator inside ensures efficient cooling, although this part can add to the cost. The unit comes pre-charged with refrigerant, which simplifies installation and avoids extra hassle or expense.
